THE DYNAMICS OF DELINQUENT PEERS AND DELINQUENT BEHAVIOR*

This analysis examines the dynamic reciprocal relationship between delinquent peer associations and delinquent behavior. It tests the hypothesis, derived from learning and interactional theories, that delinquent peers and delinquent behavior are reciprocally related—delinquent peer associations foster future delinquency, and delinquency increases the likelihood of associating with delinquent peers. It also tests the competing hypothesis, derived from control theories, that delinquent peers do not cause delinquency, but instead, the relationship is (1) spurious due to individual criminal propensity, (2) a result of the effects of delinquent behavior on future associations with delinquent peers, or (3) an artifact of problems of measuring delinquent peers. To test these propositions, we use data from the National Youth Survey and estimate a cross-lagged panel model that corrects for measurement error in indicators of delinquent peers and delinquent behavior. The model species a covariance structure model for ordinal measures. Parameters are estimated by (1) estimating a threshold model relating ordinal measures to continuous latent variables; (2) estimating a matrix of polychoric correlations relating observed variables, and (3) using an asymptotic distribution-free estimator to estimate structural parameters. The results suggest that delinquent peer associations and delinquent behavior are reciprocally related, but the effect of delinquency on peer associations is larger than that of peer associations on delinquency.     

DELINQUENT PEERS,BELIEFS, AND DELINQUENT BEHAVIOR: A LONGITUDINAL TEST OF INTERACTIONAL THEORY*

Three theoretical models of the interrelations among associations with delinquent peers, delinquent beliefs, and delinquent behavior are examined. The socialization model views delinquent peers and beliefs as causally prior to delinquent behavior, whereas the selection model hypothesizes that associations with delinquent peers and delinquent beliefs are a result of delinquent behavior. The interactional model combines aspects of both the socialization and the selection models, positing that these variables have bidirectional causal influences on one another over time. Data to test for reciprocal causality are drawn from three waves of the Rochester Youth Development Study. Results suggest that simple unidirectional models are inadequate. Associating with delinquent peers leads to increases in delinquency via the reinforcing environment of the peer network. Engaging in delinquency, in turn, leads to increases in associations with delinquent peers. Finally, delinquent beliefs exert lagged effects on peers and behavior, which tend in turn to “harden” the formation of delinquent beliefs.     

ADAPTING TO STRAIN: AN EXAMINATION OF DELINQUENT COPING RESPONSES*

Strain theories have conceptualized delinquency as a form of adaptive, problem-solving behavior, usually committed in response to problems involving frustrating and undesirable social environments. The most recent version of strain theory, Agnew's general strain theory, provides the most complete formulation of this argument by suggesting that delinquent behavior enables adolescents to cope with the socioemotional problems generated by negative social relations. To date, however, the actual coping effectiveness of delinquency remains unexamined. This study explores the ways that delinquency may enable adolescents to cope with strain, and it uses national survey data to test the coping effectiveness of delinquent behavior. The findings indicate that delinquency enables adolescents to minimize the negative emotional consequences of strain, and they provide empirical support for the interpretation of delinquency as an adaptive response to aversive environments. Implications for criminological theory are discussed.     

IMPACT OF A YOUTH SERVICE CENTER

The influences of a Youth Service Center are assessed in two South Philadelphia police districts and two pairs of selected comparison districts, using Uniform Crime Reports (UCR) and the Youth Center's caseload arrest data. UCR data indicate a slight change in arrest rates within the selected target districts and fluctuating rates within comparison districts. Data for Youth Center Clients show a 26% decrease in arrests during a oneyear period, particularly for white youths. but analysis of other important factors that may have an impact on arrest rates suggests thar it is impossible at this time to demonstrate that the Youth Service Center is significantly decreasing official juvenile delinquency.     

THE CONTRIBUTION OF GANG MEMBERSHIP TO DELINQUENCY BEYOND DELINQUENT FRIENDS*

Both being involved in a gang and having friends who are delinquent have been shown to contribute to an individual's own delinquency. However, the unique contribution of gang membership to delinquency, above and beyond having delinquent peers, has not been well studied. Increased delinquency among gang members may not be due to gang membership per se, but to the members' association with delinquent peers. Using data from the Seattle Social Development Project, this research compared involvement in delinquency for gang members, nongang youths with delinquent friends, and nongang youths who did not have delinquent friends. MANOVA and follow-up ANOVA were conducted to determine differences on measures of delinquency among the three groups at ages 14 and 15. Gang members were found to have a higher rate of offending in the past year when compared with the other groups. The contribution of gang membership to delinquency above and beyond having delinquent friends was also examined using structural equation modeling. Gang membership was found to independently predict both self-reported and officially recorded delinquency beyond the effects of having delinquent friends and prior delinquency. Implications of the results for delinquency prevention and intervention efforts are discussed.     

THE INFLUENCE OF DELINQUENT PEERS: WHAT THEY THINK OR WHAT THEY DO?*

Although the association between delinquent friends and delinquent behavior is well established, the mechanism by which delinquency is socially transmitted remains unclear. Sutherlands theory of differential association holds that delinquency is a consequence of attitudes favorable to the violation of the law, attitudes that are acquired through intimate social interaction with peers. An analysis of data from the National Youth Survey indicates that peer attitudes do affect delinquency. But the effect of peers'attitudes is small in comparison to that of peers behavior, and the effect of peers'behavior remains strong even when peers, attitudes and the adolescent's own attitude are controlled. Moreover, when the behavior and attitudes of peers are inconsistent, the behavior of peers appears to outweigh or override the attitudes of peers. These findings suggest that delinquency is not primarily a consequence of attitudes acquired from peers. Rather, it more likely stems from other social learning mechanisms, such as imitation or vicarious reinforcement, or from group pressures to conform.     

SIBLING INTERACTION AND SELFREPORTED DELINQUENT BEHAVIOR: A STUDY OF 265 TWIN PAIRS*

The relationship between the quality of twins’mutual attachment and delinquency is examined in a study of 265 twin pairs. It is predicted that twins with stronger mutual attachments will have lower rates of delinquent behavior. Contrary to this prediction, twins’mutual attachment (that is, the frequency with which the twins saw each other in teenage activities) is found to be unrelated to delinquent behavior. The twins often cooperated, however, in their delinquent acts: 61 % of the girls and 79% of the boys reported committing one or more delinquent acts with their twins. In accord with social control theory, social bonds (normlessness, perceived parental acceptance-rejection, and value placed on academic achievement) are strongly associated with delinquent behavior. Except for male DZ twins, however, these same variables are only weakly associated with twins’mutual attachments. A behavioral genetic analysis of the social bonds indicate both genetic and specific environmental components to their variation but fail to show evidence of a shared environmental component. Implications of these findings are discussed.     

SOCIAL CLASS AND DELINQUENT BEHAVIOR

The apparent refutation by self-report studies of social class-related theories of juvenile delinquency is critically reviewed. Improper conceptualization and operationalization of “social class” are considered to be primary causes of inconsistent findings. A more appropriate “underclasslearning class” model of stratification is suggested. Although no empirical support is found for a relationship between self-reported delinquent behavior and socioeconomic status of father's occupation. indications are that social class is somewhat more related to self-reported delinquency using the underclass/earning class model. However, there is no reason to expect social class to emerge as a major correlate of delinquent behavior no matter how it is measured.     

SOCIAL CONTROL AND SOCIAL LEARNING MODELS OF DELINQUENT BEHAVIOR A Synthesis

Social control and social learning models of delinquent behavior are reviewed and compared. The data analysis shows that predictions from the social learning model ficrther specify the control perspective. Thus, attachments are an important influence on delinquent behavior only when the source of attachment is taken into consideration, Further, the data presented suggest that observational learning has an influence on delinquent acts as suggested by social learning theory. Particular parental behaviors which influence the reinforcing value of the home appear to have the primary influence on delinquent behavior in the parent/child bond. From this study, it is concluded that a combination of the social “bonding” notion from control theory along with specific principles of social learning lay the groundwork for a more comprehensive theory of delinquent behavior than either perspective alone.     

DELINQUENT PEERS IN CONTEXT: A LONGITUDINAL NETWORK ANALYSIS OF SELECTION AND INFLUENCE EFFECTS*

In this article, longitudinal social network data are analyzed to get a better understanding of the interplay between delinquent peers and delinquent behavior. These data contain detailed information about the social networks of secondary school students from the same grade, their delinquent behavior, and many relevant correlates of network formation and delinquency. To distinguish selection and influence processes, a method (Simulation Investigation for Empirical Network Analyses, SIENA) is used in which network formation and changes in delinquency are simulated simultaneously within the context of other network processes and correlates of delinquency. The data and the method used make it possible to investigate an unusually wide array of effects on peer selection and delinquent behavior. The results indicate that similarity in delinquency has no significant effect on the selection of school friends when other network dynamics are taken into account. However, the average delinquency level of someone's friends in the school network does have a significant, although relatively small, effect on delinquent behavior of the respondents, beyond significant effects of changes in the level of self‐control and morality. Another peer‐related change, leaving or joining informal street‐oriented youth groups, also appears to have a substantial effect on changes in delinquency.     

CO‐OFFENDING AND THE DEVELOPMENT OF THE DELINQUENT CAREER*

This article examines the role of co‐offending in the development of the delinquent career. Hypotheses derived from Reiss's (1986, 1988) taxonomic theory of co‐offending are tested, using police‐reported data on the delinquent careers and co‐offending of 55,336 Canadian offenders. Support is found for a taxonomic theory and for age‐related and functional theories of co‐offending. The taxonomy consists of two types of offenders—high activity (3 percent) and low activity (97 percent)—whose co‐offending patterns differ during the teenage years but not during childhood. For low‐activity offenders as teenagers, the proportion of co‐offenses decreases with criminal experience. The rate of co‐offending by high‐activity offenders as teenagers is lower at onset than for low‐activity offenders, and it varies little with criminal experience. For both offender types, the proportion of co‐offenses decreases with age, is slightly less in males, and varies with the type of offense. For both offender types, the proportion of co‐offenses in childhood offending is greater than in the teenage years and is unrelated to the offender's age or criminal experience.     

A MULTISITE EXAMINATION OF YOUTH GANG MEMBERSHIP: DOES GENDER MATTER?*

The nature and extent of female involvement in gangs has been a relatively neglected area of criminological inquiry. Even more rare have been investigations of explanations of female gang participation. This neglect can be attributed, in large part, to a perception that the phenomenon is statistically rare and the behavior substantively unimportant. Our objectives in this research are twofold: to describe gang membership in a general survey of eighth-grade students in a cross section of the United States and to examine differences between boys' and girls' attitudes associated with gang membership     

EXPLAINING THE GENDER DIFFERENCE IN ADOLESCENT DELINQUENT BEHAVIOR: A LONGITUDINAL TEST OF MEDIATING MECHANISMS*

The extent to which mediating mechanisms account for the gender difference in delinquency was tested on a sample of 2, 753 adolescents studied across three points in time. Results using structural equations modeling showed that males are more likely to be involved in delinquent activities, partly because they are less bound to conventional values, more likely to be associated with delinquent peers, and report more adverse experiences with the authorities. These effects remain after partialling out the stability effect of prior delinquency and other sociodemographidstructral variables. However, although males are more likely than females to report frustration in achievement, frustration in achievement does not directly affect subsequent delinquent behavior in a multivariate context. In addition, adolescent males and females tend to report similar patterns of delinquent activities, and the influences of mediating variables on delinquent outcome are generally similar for males and females.     

THE TIMING OF DELINQUENT BEHAVIOR AND ITS IMPLICATIONS FOR AFTER-SCHOOL PROGRAMS*

Research Summary: This study examines self-reports from two samples to assess the timing of delinquency. Results imply that the after-school hours are a time of elevated delinquency, but that the peak is modest compared with that observed in official records. Additionally, children who are unsupervised during the after-school hours - the primary target population for after-school programs - are found to be more delinquent at all times, not only after-school. Policy Implications: This finding suggests that factors (including social competencies and social bonding) in addition to inadequate supervision produce delinquency during the after-school hours and that the effectiveness of after-school programs for reducing delinquency will depend upon their ability to address these other factors through appropriate and high quality services.
